Support for Azure Disk Encryption-protected machines
We need to be able to use ASR to protect/replicate Azure virtual machines protected by Azure Disk Encryption.
VMs enabled for encryption with Azure AD app are supported. Refer this to enable to enable replication of Azure disk encryption (ADE) enabled VMs, from one Azure region to another – https://docs.microsoft.com/en-us/azure/site-recovery/azure-to-azure-how-to-enable-replication-ade-vms
I was able to accomplish this successfully untill it's officially supported

Ideally there would be an option to enable disk encryption on the replica disk in the DR site. Currently it isn't possible to add an Azure VM to ASR when ADE is enabled but the workaround is to add the VM to ASR before ADE is applied. And use the console to enter the recovery key when the failover has taken place. This workable for a few VM's but for complete site failover this unmanageable.
